Answer:
HYDRA
Explanation:
The nerve cells are scattered in each layer of the body wall and these neurons send information from sensory organs. Based on the given choices above, the organism that has a nerve net that allows it to respond to a stimulus in a coordinated way is the HYDRA.
Hello,
concentration gradient<span> is the process of particles, which are sometimes called solutes, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles. The areas are typically separated by a membrane.
correct me if i'm wrong!
But since concentration gradient is the process of particles, then </span><span>Sedimentation is the tendency for </span>particles<span> in suspension to settle out of the fluid in which they settle as individual </span>particles<span> and do </span>not<span> flocculate</span><span>

Answer:
The advantage of inside fertilization is that the fertilized egg is protected against dehydration on land. The embryo is segregated from the woman, limiting young predation. The fertilization of internal eggs by a certain male is also improved.
Explanation:
Interior fertilization is the union in the female body of the egg and the sperm. The female has more control over internal fertilization, as opposed to its counterpart, exterior fertilization. There has to be a technique for males to introduce the sperm into their reproductive system in order for internal fertilization to occur.
Copulation, an intromittent organ, is inserted into the vagina or cloaca in mammals, reptiles, and some other group of species. The cloacal kiss is employed in most birds, and the two animals squeeze their cloacas together as sperm is transferred. Salamanders and Spiders are internally regulated by passing a bundle of sperm from the male to the female. Some insects and certain mollusks are fecundated. The embryos are placed as eggs in the organisms or continue to develop within the mother's reproduction tract as young, viviparous creatures after fertilization.
